MACHINE Eon MOLDING rLAsTIo'ooNrEoTIonsL Application filed September 3, 1921, Serial No. 498,494, and in Great Britain January 26, 1914.

(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. L, 1313.)

This invention relates to the molding of chocolate and like plastic materials in the manufacture of confectionery, and comprises novel means for use with molds of sectional or divided character whereby an individual or separate deposit of material may be effected in each section or division of the mold each mold being filled with a measured quantity of material.

The invention further consists, in a de positing machine for example, for dealing with chocolate, in the provision of a die proure 3 is a partial plan view of the improved form of die, andiFigure l is a plan view of a sectional mold of conventional form.

Referring to Fig. 1, the portion of the machine illustrated, which is merely given as an example, comprises the rolls a which force the material from a hopper I) through a spout 0 provided with scrapers cl and through a channel 6 in a rotary valve f into a measuring cylinder 9 containing a plunger h which, when the valve is rotated, is actuated to force the material from said cylinder through the outlet 2'.

This construction of machine is well known in, the art, but according to this invention I provide below said outlet 11 a die or nozzle j mounted 1n dovetail guides /tin the machine framing so as to be readily removable, this die comprising one or more series of separated apertures j spaced apart at such distances that each aperture will cause an individual or separate quantity of material to be deposited centrally into a section or division Z of a mold m below said die and which may be caused to travel intermittently through the machine, for exprises thirty-two sections or divisions, where- 31;

as the die shown contains but sixteen discharge apertures, so that it is, necessary to first bring the front portion of the mold beneath the die for filling the first sixteen sections, and. then to move ,the mold to bring its rear part below said die for filling the remaining sixteen section-s, this method being preferable to providing. the die With thirty-two discharge apertures, since the amount of feed or skip of the conveyor n and consequently of the molds between each period of rest for filling need not be excessive. However, any arrangement of the discharge apertures and molds with corresponding sections may be used according to requirements, obviously for the groups of molds it is advantageous to fill the complete mold at one discharge.

The die may contain any number of series of discharge apertures according to the Width of the machine for filling a corresponding number of rows of molds fed along on the conveyor, and it will be apparent that by the method of mounting the smaller the die being formed of an elongated plate provided Withlongitudinally spaeed depressions, the bottom of each depression having separate discharge apertures spaced apart at such distances as to correspond with the compartments of the mold, and. a removable strainer received in oath of the depressions and positioned above and over the apertures in the, bottom 01 the depression, the'etrainers being normally movable With the die. 1U In Witness whereof I have signed this specification. 7 I
